I've started a new game with the compass disabled. I found the game much more immersive, I'm now more aware of my surroundings, and it makes exploring fun. The only problem is finding some quest targets, but at least Clairvoyance will have some use now - or so I thought.
That spell is worse than any GPS. It always has to find the nearest road, and then sticks to the paved way only. It leads you through all the S-turns and curves and whatnot, leading on the longest way possible. Tell me, why, oh why does it not show the straight route to the target, and lets me decide if I want to check out all the tourist attractions of the hold along the way?
